GEORGE L. WELLER, OF ELYRIA, OHIO.

FLUSH-TANK REGULATOR.

To all whom it may concern:

Be it known that I, GEORGE L. WVELLER, a citizen of the United States,residing at Elyria, in the county of Lorain and State of Ohio, haveinvented certain new and useful Improvements in Flush-Tank Regulators;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to flush tank regulators and has for its objectto construct a device of this nature which will give a constant supplyof water for automatic flush tanks in sewerage systems.

It further provides a means whereby a desired number of flushings may behad per day by the regulation or change of the strainer, as willhereinafter be more fully described.

With the above and other objects in view, this invention consists in theconstruction, combination and arrangement of parts, all as hereinaftermore particularly described, claimed and illustrated in the accompanyingdrawings, wherein:

Figure 1 is a central, vertical section, parts thereof being inelevation, of a device constructed in accordance with the presentinvention; Fig. 2 is a top plan view thereof; Fig. 3 is a verticalsection of a strainer con tained within the valve constituting thepresent invention; and Fig. 4: is a horizontal section taken along line4t 1 of Fig. 1.

The regulator forming the subject matter of the present inventionconstitutes a valve casing havin oppositely disposed inlet and outletports. A cylinder is rotatably mounted within the casing and is providedwith a rectangular projection at its upper terminal, which projects outof said casing. This projection carries a projecting screw, whichcooperates with a pair of diametrically disposed stops formed on thecasing for regulating rotation of said casing. A plurality of openingsare formed in said casing whereby the passage of water therethrough mayreadily be regulated. Oppositely disposed to the projection carried bysaid cylinder, and operable within said cylinder, is a tubularprojection retained therein by a wing nut, said tubular member havingthe wall thereof pierced by a plurality of slits, through which thewater, as will hereinafter be more fully described, is adapted to pass.A

screen ora plurality thereof, as desired, is mounted within the tubularmember, and is adapted to strain and cleanse the water passingtherethrough, as will be described more clearly hereinafter.

Reference being had more particularly to the drawings, 10 indicates avalve casing of any suitable construction, preferably, however,cylindrical, having located adjacent to its upper terminal the inlet andoutlet port 11 and 12 respectively. A cylinder 13 is mounted within thecasing 10, said cylinder being closed at its outer terminal and providedwith an inwardly extending circumferential flange at its lower terminal.The upper terminal of the cylinder 10 is provided with a transverselyarranged rectangular extension 15, which projects from the casing 10. Apair of diametrically disposed stops 16 are formed upon the casing 10and cooperate with the screw 17 carried by the extension 15 for limitingthe rotary movement of the cylinder 13. The cylinder 13 is piercedadjacent to the inlet and outlet ports 11 and 12 respectively by theoppositely disposed openings 18, which are adapted to coincide with theinlet and outlet ports 11 and 12 when the screw 17 is positioned asillustrated in dotted lines in Fig. 2. The cylinder is likewise providedwith a similar opening 19 which is adapted to coincide with the inletport 11 when the screw 17 bears against one of the stops 16, andregisters with the outlet port 12 when the screw operates against theopposite stop 16.

A collar 20 is threaded upon the lower terminal of the casing 10 and hasdetachably mounted therein a wing nut 21, said wing nut removablycarrying a tubular member 22. This tubular member 22 is provided withthe opposite disposed transversely arranged slits or openings 23, and isprovided at its base with a screen 24.

The wing nut 21 is provided with a passage 25 therethrough, the upperterminal of which is greatly reduced. This passage is for the regulationof the number of flushings in a given time, by reason of the fact thatthe reducedportion of the passage 25 is of such size that only a knownamount of water can pass therethrough in 2 1 hours. lVhen the port 19 ofthe cylinder 13 registers with the inlet port 11, the outlet port 12 isclosed, thus permitting the water to flow through the slotted cylinder22, the screen 24 and out through the passage 25 into the flushing tank.A, tubular slotted cylii'idrical member 22 in combination with thescreen Ql prevents any sediment or foreign matter from entering thereduced portion of the passage 25, thereby clogging the same. The minutesides of the reduced portion of the passage is of such construction thata very small amount of sedimentwould clog the same, thereby renderingthe valve useless. If so desired, the cylinder 13 may be turned toregister the port 19 with. the escape 12, thus closing the supply andpern'iitting the wing nut to be removed for the cleansing of theinterior of the valve. If so desired, the ports 18 may coinciderespectively with the ports 11 and 1:2, thus permitting the water topass directly through the valve and out of the escape 12.

Having thus fully described my invention, what I claim as new, anddesire to secure by U. S. Letters Patent, is:

1. .ln a device of the character described, the combination with acasing, of inlet and outlet extensions formed on said casing, a cylindermounted in said casing adapted to regulate the flow of liquidtherethrough, a closure carried by said casing having a re strictedopening therethrough, and a tubular member carried by said closure andcommunicating with said opening in the closure.

2. In a device of the character described,

the combination with a casing, of inlet and outlet extensions formed onsaid casing, a cylinder mounted in said casing adapted to regulate theflow of liquid therethrough, a closure carried by said casing having arestricted opening therethrongh, and a tubular member carried by saidclosure communicating with the restricted opening therein and saidtubular member also provided with openings communicating with theinterior of the cylinder.

3. In a device of the character described, the combination with acasing, of inlet and outlet extensions formed on said casing, a cylindermounted in said casing adapted to regulate the flow of liquidtherethrough, a closure carried by said casing having a. re-- strictedopening therein, and a tubular member carried by said closurecommunicating with the restricted opening therein, said tubular memberbeing provided with a plurality of oppositely disposed transverse slotsproviding communication between the interior of said tubular member andthe cylinder aforesaid.

In testimony whereof I affix my signature in presence of two witnesses.
